I do believe there are additional mods on a DPV than just the retaining screws. I cant quote exactly, but I believe he bored out a bunch. Since it is his business, I wouldnt expect him to share specifics, but he might.
Am I understanding right that with the change in the three screws you can safely fill the standard Disco tube to 3000 psi?Ed
The DPV valve is a highly modified factory Disco valve and being able to get 30 great power shots in the low to high 40 FPE will not be easy to match. JSP Monsters 25.39 gr. at 49.46 with 30, shots is pretty amazing from a DiscoNorm
A big hello to you WilliamYes a good Disco, and it is not too difficult to make them extremely good should be a must for everyone.My little Disco FTs are going to be a winner! You may just need one. Norm

You may can buy a complete valve from Norm at Discos R US that is already setup for the 3k fill. The D.P.V. (Disco Power Valve) Valve is made for a 3000 PSI fill. http://discosrus.net/disco/Contact Norm and he should be able to take care of it if you want too fill higher, you can just modify your valve if you want! Best to let someone do it that is experienced! I tried and messed up a valve...The weakest point on a Disco is the 3 valve bode 8-32 screws, changing those to a bigger one increases the Safety margin a good bit. Williami was thinking of buying this but isn't $85 sort of expensive? I'm pretty sure the valve from crosman is $15 and the only modification he does as far as i can tell is retap it for bigger screws.

yeah I guess if the valve is highly modified $85 is more than reasonable... I thought it was simply a stock valve but retapped for bigger screws. 30 shots at 40 fpe.. wow! is that with the standard disco airtube or a bottlefed one? If its the first one i will definitely have to pick one up..might be awhile though since i'll need to sell my pump for a scuba setup since pumping to 3k psi sounds like some pain
